China told to IMMEDIATELY stop new tests on mutant Covid strain with '100% fatality rate'

Covid scientists are being warned against researching on a new mutated strain that caused a 100 per cent fatality rate in "humanised mice".

The deadly virus, known as GX_P2V, attacked the brains of mice that were engineered to reflect similar genetic makeup as humans.

Researchers noted a "surprisingly" rapid death rate after all the mice infected died within just eight days.

Within the days before their deaths, the rodents had quickly lost weight, exhibited a hunched posture and moved extremely sluggishly.
